Condition

Some customers may comment about one or more of the following conditions:

- Intermittent no start
- Intermittent extended crank
- Intermittent start then stall
- Intermittent check engine light illuminated
- Intermittent reduced power steering assist
- Intermittent airbag light illuminated
- Intermittently functioning or inoperative electrical systems

Upon investigation, the technician may find DTC P0442 or P0449 set as current or in history. These DTCs may also be accompanied by other DTCs.

Cause









These conditions may be caused by poor electrical contact between the underhood fuse block (UBEC) and its connectors. This poor contact may be due a bent or twisted male terminal (as shown above) on the UBEC side. During assembly when the UBEC is bolted to the connectors, the male terminal contacts the edge of the mating female terminal and pushes the terminal (1) out of the cavity. When this occurs, the terminal lock on the connector breaks and the terminal will no longer lock into the connector.

Correction

Remove the UBEC from the connectors. Visually inspect the suspect connector to see if the terminal has been pushed out of its cavity. If the terminal has been pushed out of its cavity, the terminal lock is damaged and connector replacement is required. Also, inspect the terminal for damage and replace if necessary. Straighten the UBEC male terminal (use a business card as a straight edge). If the terminal is twisted, attempt to straighten it using needle nose pliers.
